Ultrasonographic monitoring of limb lengthening

N Maffulli, T Hughes, and JA Fixsen

Hospitals for Sick Children, London, England.

Limb lengthening in nine patients was monitored by radiographs and by ultrasound scans. The distraction gap appeared as a sonolucent area within which echogenic foci developed soon after distraction commenced. By seven weeks a new cortex was detected, and medullary canal began to develop between seven and eight weeks. Ultrasound scanning can be used to measure distraction, but it was not as useful as radiographs in detecting angulation. Its use in patients undergoing limb lengthening could reduce their exposure to radiation.
